BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine, more specifically, using a game medium (for example, a pachinko ball), and an appearance rate of a predetermined stop mode (for example, reach pattern) of a variable display game on a variable display device. The present invention relates to a gaming machine in which can be set to a predetermined probability.

[0002]

2. Description of the Related Art Generally, for example, a pachinko machine is a typical game machine using balls as a game medium. There is a model in which a big hit game state (a special game state, hereinafter, simply referred to as a big hit state) occurs in the process of playing a game with a gaming machine. Is inviting.

In a conventional gaming machine, for example, a gaming machine belonging to the so-called first type, the display symbol of a plurality of digits of a variable display device is changed, and a variable winning device or the like is played for a predetermined period based on a special combination of the stop symbols. We are playing a special game (big hit game) that changes to an advantageous state. In this case, a specific game that is advantageous to the player (for example, the special winning opening is 30
A game content that is opened for a second or until the winning ball is counted 10 times) a predetermined number of times (for example, 16 cycles)
Only games can be played.

[0004]

By the way, in the conventional gaming machine, after winning the first-class starting opening, a big hit random number is taken in, and the random number taken in when the special figure rotation is started and the preset judgment value. After comparing and judging, the stop symbol corresponding to the result is taken in, and thereafter, since the game process is configured to proceed with this stop symbol, even if the stop symbol is a so-called reach symbol, from the result of the comparison judgment Subsequent processing will proceed according to the captured stop symbols, and the appearance rate of the reach symbols will be uniform and there will be a problem that the game is not interesting.

In other words, as the business form of the hall, it is preferable that the appearance rate of the reach symbol varies depending on the time zone and the customer base even if the same model is used, but at present, the appearance rate of the reach symbol cannot be changed. Therefore, the degree of freedom of the business form of the hall was low. On the other hand, for the player, if the appearance rate of the reach symbol is different even for the same model, it is more entertaining and interesting, but at present it is not possible to change the appearance rate of the reach symbol, and respond to such demand. I couldn't.

The reach symbol means, for example, when there are three stop symbols, the first stop symbol and the second stop symbol are the same symbol (doublet). Therefore, if it is a reach symbol, after all, if all three symbols are the same,
Alternatively, the two predetermined symbols are the same and the last symbol is different from each other.

Therefore, the present invention has an object to provide a gaming machine in which the appearance probability of a reach symbol can be set, which is rich in amusement and is more interesting and which can increase the degree of freedom in the business form of a hall. There is.

[0008]

To achieve the above object, a gaming machine according to the present invention has a variable display device 102 for variably displaying a plurality of pieces of identification information, and a specific game state in which variable display on the variable display device 102 can be started. Specific game state detection means (for example, CPU 301, ROM 30) for detecting that
(2, RAM 303, EEPROM 304) and a variable display game in which the identification information of the variable display device is variably displayed, and a game in which a special game value (eg, big hit state) is given to the player based on the stop identification information mode. Control means 401 (eg CPU 301, ROM 302, R
AM303, EEPROM304), in the gaming machine (for example, pachinko machine 1) equipped with, the appearance rate of the predetermined stop mode of the variable display game on the variable display device,
It is characterized in that a predetermined stop mode appearance rate setting means (for example, a probability setting switch 325) for setting a predetermined probability is provided.

As a preferred mode, in the gaming machine according to claim 1, the predetermined stop mode appearance rate setting means sets a probability of the reach rate of the reach symbol as a predetermined stop mode of the variable display game on the variable display device. Characterize.

In the gaming machine according to claim 1, a setting state informing means (for example, probability setting display LEDs 232, 23) for informing the setting state of the predetermined stop mode appearance rate setting means.
3) is provided.

[0011]

In the present invention, the hall staff operates the predetermined stop mode appearance rate setting means to easily change the appearance rate of the reach symbol to a predetermined probability. Therefore, since the appearance probability of the reach pattern can be easily changed according to the model and the business form of the hole, the game is rich, the game is more interesting, and the flexibility of the business form of the hole can be increased.

For example, the present invention can be applied to an enclosed ball type gaming machine (for example, a credit type gaming machine) in a complete card type pachinko gaming system. Further, it is not limited to the example in which the magnetic card is used as the game card, and for example, a game machine using an IC card may be used. When an IC card is used, as a matter of course, the card reader or the card reader / writer that corresponds to the IC card is used.

Next, the game board 13 is an area for making a judgment of out or safe while dropping the fired pachinko balls from above, and when a ball enters the winning opening and is effectively safe, a predetermined number of prizes are given. The balls are discharged from a ball discharging device described later and are supplied to the upper plate 21. Even if the ball is fired by operating the firing operation knob 34, the pachinko ball returns to the firing position or is discharged to the ball storage tray 32 when it becomes a foul.

Here, if the game area on the game board 13 uses a game medium and a plurality of pieces of identification information are variably displayed and the game proceeds, the present invention is applicable. For example, what belongs to a so-called "first type" or a "third type" that uses a variable display device is an application of the present invention.
Even other types of pachinko machines are applicable as long as they use a variable display device to variably display a plurality of pieces of identification information to advance a game.

The game area can have any configuration within the scope of the present invention. As an example, in the present embodiment, the “first
It uses the type that belongs to "seed". Therefore,
The application of the present invention is not limited to the type belonging to the “first type” shown in FIG. 2, but can be applied to a wide range of gaming machines as described above. For example, the present invention can be widely applied to those in which a game is performed by changing the symbol content of a video display device which has been remarkably developed recently, those in which a character game is equipped with a liquid crystal, a color TV, and the like.

FIG. 2 is a front view showing a game area of the game board 13. In FIG. 2, a rail 1 having a function of guiding a ball ejected around the game area to an upper portion of the game area or guiding an out ball collection port 135 described later.
01 is arranged. Further, a variable display device (a so-called accessory device, which corresponds to a video display device) 102 capable of displaying a video is arranged in substantially the center of the game area. Below the variable display device 102, a start winning port 103 is arranged, and depending on the symbol display result of the variable display device 102, a large winning port that changes from a first state in which a game ball is not accepted to a second state in which it is easily accepted A variable winning device (a big winning opening, so-called attacker) 104 is arranged. FIG. 2 shows a case where the variable winning device 104 has changed to a second state in which it is easy to accept game balls.

Reference numerals 105 and 106 denote start winning openings, 107 and 1
Reference numeral 08 is a general winning opening, 109 and 110 are decorative members that can be turned on and can also rotate as a windmill, 111 and 112 are side lamps, and 113 and 114 are decorative lamps. Side lamps 111 and 112 and decorative lamps 113 and 11

Reach indicator 12 that lights up
2. A special reach indicator 123 that is turned on when the display pattern of the variable display device 102 is a special reach is arranged.

Special reach (also referred to as super reach) means that after stopping the first and second symbols, the third symbol is stopped at a special stop different from the normal stop when the third symbol is stopped. For example, so-called long reach is adopted as a special stop. Specifically, the first left symbol is "2", the second right symbol is also "2", and the third middle symbol is scrolling very slowly before "2". Is called long reach. Therefore, during the period related to the stop in the special stop, the scroll of the symbols becomes more gradual. As a result, the player can enjoy the real pleasure of long reach for a long time, which is very "exciting".

The variable display device 102 is a start winning port 103,
When a ball is won in 105, 106, the display symbol is changed, and when the symbol is in a specific profit state (that is, in the special game state, for example, the state of a big hit, "Zero" state: "777", etc.) The device (attacker) 104 is opened. In addition, a so-called sky entrance (a reference numeral is omitted because it is hard to see in FIG. 2) is formed on the upper part of the variable display device 102, and this is also a general prize. Further, a plurality of hitting ball direction changing members 131 to 134 called windmills are rotatably installed at appropriate positions in the game area, and a large number of obstacle nails (not shown) are also implanted. In addition, an out ball collection port 135 is formed in the lower center of the game area.

Here, as the variable display device 102, one that can display an image using a fluorescent display (FIP) is used, and the details of the image display portion 102A are shown in FIG. In FIG. 3, the image display section is roughly divided into three parts.

3 ”) etc. can be displayed. The contents to be displayed on each of the grids 141 to 143 are V data, which will be described later, in units of grids as video data.
-Temporarily stored in the RAM 354, read at a predetermined display timing, and lighting-controlled for each grid. In this case, the V-RAM 354 stores the special figure and the data of the start memory display.

The data of the start memory display corresponds to the data of the so-called start memory display, and the start winning opening 1
When a ball wins any of 03, 105, 106, 4
This is data for displaying that the number of winning balls has been stored within the range of individual pieces. Starting winning holes 103, 105, 106
A continuous jackpot within a range in which four winning balls are stored (hereinafter, referred to as a starting storage range) is usually referred to as a pure ream chan (or simply ream chan). According to this, the number of payouts to the player is significantly increased.

The display of the starting memory is performed by the tulip type fluorescent display in the second grid 142. When there is no starting memory, the fluorescent display 151 and the fluorescent display 152 are turned on, and the other fluorescent display 153 and The fluorescent display 154 simulating a number is turned off. On the other hand, when the start-up memory is generated, the fluorescent display 151 is turned off, the fluorescent display 152 continues to be lit, and the fluorescent display 153 and the fluorescent display 154 simulating a numeral are turned on.

As a result, an image as if the tulip was opened is displayed, and the player is informed of one start memory display. The same applies to the second and subsequent starting memory displays, and the fluorescent indicators 155 to 157 simulating numbers are sequentially turned on. In this way, depending on whether the tulip is closed or opened, the starting memory number is displayed within the range of 4 by the fluorescent display. In this embodiment, the variation time of the symbol changes based on the number of starting memories, for example, when the number of starting memories is small, the variation time of the symbol is long, and when the number of memories is large, the variation time of the symbol is short. It is designed to control.

Round fluorescent display (eg fluorescent display 16
1) is an image of a pachinko ball, and it is made to look like a pachinko ball with a pattern in which white glittering points are reflected on a blue background. Then, when the special figure is not displayed, the fluorescent display 161 is turned on as the lighting start position, and the pachinko ball is ejected from the firing position and moves to the game area. , The fluorescent displays 162 to 170 are sequentially turned on).

When the special drawing is not displayed, other displays such as a call-in display, a fanfare display for notifying the big hit occurrence, a big hit display, an interval display, and a display at the end of the big hit are displayed. As an example, the call display is
A large number of round fluorescent indicators (for example, fluorescent indicator 14) that image a pachinko ball placed in the center of the three control areas.
4, 145, 146, etc.), for example, a call-in message such as “Irasha Imase! Honjitsu Daikaihou” can be displayed.

3 displays the set value of the reach rate of the symbol variation. 2
It is also possible to directly display the jackpot probability or the reach rate itself by two probability setting display LEDs 232 and 233 in a two-digit numerical value.

Although the set values are displayed on the probability setting display LEDs 232 and 233, they are kept secret so that they will disappear and cannot be seen from the outside after a certain time has passed after the setting operation. The change in the jackpot probability and the reach rate of the variable display device 102 is not limited to the above-described three steps or six steps, and other changes may be made. In addition, probability setting display LEDs 232, 23 are provided at the end of the accessory control circuit board 206.
3 and various connectors 234 (numbering is omitted for other connectors) are arranged.
Thus, the accessory control circuit board 206 is connected to another circuit board or the like.

The firing circuit board 207 performs various controls necessary for firing balls, and the firing control circuit board is housed in a predetermined case. The speaker 208 is for notifying a sound effect necessary for a game (for example, a sound effect associated with discharging a ball) or an artificial synthetic sound, and generates various sounds according to the number of discharged balls, the prize mode and the lending of balls. Inform the player. The control circuit board is a combination of a control circuit board (that is, a board that realizes the functions of the control circuit) and a box-shaped metal or resin chassis box that houses this board. It is used as a concept including.

FIG. 4 shows a state in which the ball gathering cover (not shown) is removed, and the ball gathering cover is detachably attached to the body gathering cover main body 240. Further, the ball gathering cover closes a central opening portion that is largely opened in the center of the base frame body 210, and the central opening portion is the variable display device 1.
It is a space for installing 02. The rear side of the ball gathering cover is formed so as to bulge out, and has a structure in which the rear side of the discharge control circuit board 205 and the accessory control circuit board 206 is largely projected rearward. By closing the central opening with the ball gathering cover, balls dropped from the storage tank 201 or the like do not collide with the back surface side of the game board 13.

A relay board 241 is provided inside the ball gathering cover main body 240, and the relay board 241 serves as various electric parts (for example, lamps, solenoids, LEDs, motors, sensors) in the game board 13. The object control circuit board 206 is once relayed in the middle of the wiring for connecting the object control circuit board 206.

Next, FIG. 6 is a block diagram of a control system in the pachinko machine 1. In FIG. 6, this control system is roughly divided into CPs that perform control necessary for pachinko games and the like.

Buffer gate 309 for outputting to PU 301 and CPU
An output port 310 that receives a signal from the bus 301 through the bus 308, a driver 311 that drives a control signal input through the output port 310 to generate various drive signals and output the drive signals to each display unit, and the like. The sound generator 312 generates a necessary sound effect (or may perform voice synthesis), and an amplifier 313 that amplifies a sound signal from the sound generator 312.

Each of the circuits including the CPU 301 is realized by a board unit called a game board control device 206 including a microcomputer arranged at a predetermined position on the back side of the pachinko machine 2. The board unit of the microcomputer exchanges control signals and data with the ball lending machine 3, the island facility, the management device of the game shop, and the like. The sound generator 312 generates a sound effect necessary for the game, and the generated sound effect is amplified by the amplifier 313 and emitted from the speaker 208. In addition,
In addition to the sound generator 312, for example, voice synthesis I
C may be provided to perform a voice synthesis necessary for a game (for example, a voice that enhances the player's expectation at the time of a reach or a big hit, "yattat", "reach").

The low-pass filter 307 receives signals from the first-type starting switch 321, the continuation switch 322, the count switch 323, the probability setting switch 325, and the probability setting value display switch 326, and ejects the balls from the ejection control circuit. The request signal 327 for requesting is input. The low-pass filter 307 to the CPU 30
With respect to the signal taken in 1, the CPU 301 reads the software twice to prevent chattering in consideration of the time constant of noise and the like.

The first type starting switch 321 is the starting winning opening 1
It is detected that a ball is won in 03, 105, 106.
Continuation switch 322 is the variable winning device 1 as a big winning opening
It is arranged at 04 and detects that a ball has won a so-called V winning opening. The count switch 323 is the variable winning device 1
When 04 is opened, a winning ball is detected in the variable winning device 104. Each of the above detection switches is composed of a proximity switch and detects a ball based on a change in magnetic force caused by the passage of the ball.

The first type starting switch (specific game state detecting means) 321 detects the starting winning.
This start winning state corresponds to the detection of the specific game state, and means that the state has become the specific game state in which the variable display on the variable display device 102 can be started. The specific game state is not limited to the example of the detection by the first-type start switch 321, but for example, the variable display on the variable display device 102 can be started when the ball passes through a predetermined gate (for example, a normal pattern gate). It may be in a game state, in which case a sensor (specific game state detecting means) for detecting passage of a gate is provided, and variable display on the variable display device 102 is started by a passage detection signal from this sensor.

Here, the universal design gate is provided at a specific position on the game board 13, and has a gate through which only one ball can pass, and when the ball passes through the gate, a normal electric starting port (this implementation) The symbol (for example, a number) of the normal symbol display arranged in (in the example is omitted) is changed, and when this number becomes a predetermined specific symbol (for example, "7"), the tulip of the normal electric starting port It is designed so that it can be electrically operated to open it for a certain period of time. Normally, the tulip of the electric starting port is normally closed, but it is controlled to open under a certain condition as described above. Also, the opening time of the tulip may be variably controlled.

When the tulip at the normal electric starting opening is opened, the winning rate to the normal electric starting opening is increased, which gives the player an advantage. Normally, the opening time of the electric starting port is set to 5 seconds when the hit symbol is "7", and is set to 2 seconds when the hit symbol is "3". Further, such control for increasing the probability of hitting a normal figure is not limited to the one based on the symbol of the normal symbol display, and may be controlled by, for example, a variable symbol of a special symbol. In that case, in the case of normal normal operation and normal big hit pattern, the probability of hitting a normal figure is set to about 1/20,
Lucky jackpot design (eg, “333”) and special lucky jackpot design (eg, “77”)
7 ") appears, control is performed to increase the probability of hitting a universal figure after the big hit to a high rate of 1/4.

By increasing the probability of hitting the ordinary figure, the winning rate to the ordinary electric starting port is increased, and the probability of a big hit next time is indirectly increased from the aspect of starting winning. Therefore, the player's motivation for playing the game is increased from the viewpoint different from the case of increasing the probability of big hit occurrence. In particular, the special symbols will rotate well, so you can play with excitement and excitement, which makes the game interesting. In addition, the change of the big hit probability may be appropriately combined with the probability of hitting the universal figure, and in this case, the game content is extremely enhanced.

The probability setting switch (predetermined stop mode appearance rate setting means) 325 is for changing and setting the big hit probability and reach probability of the variable display device 102, and the accessory control circuit board 20.
6, the switch insertion port 206a thereof is exposed and arranged on the front surface side of the accessory control circuit board 206. The probability setting value display switch 326 is an operation switch for displaying the setting value to the outside when the jackpot probability and reach probability of the variable display device 102 are changed and set, and the setting value is the 7-segment probability setting display described above. It is displayed on the LEDs 232 and 233.

The driver 311 is connected to the display control circuit 354 via a data signal line 351 for transmitting necessary data, a control code signal line 352 for transmitting a necessary control code, and a strobe signal line 353 for transmitting a necessary strobe signal. Has been done. The strobe signal indicates whether the set data signal is valid or invalid. Display control circuit 354
Is for controlling the symbol display of the variable display device (that is, the image display device) 102. For example, a CPU for a special figure display,
It is composed of an IC circuit including a font ROM and a V-RAM, generates a drive signal, and drives the variable display device 102. Further, the driver 311 outputs the transmission clock signal 361 and the prize ball data signal 362 to the discharge control circuit. CPU301, ROM302, RAM3

Configure 01.

Next, the procedure of various controls performed by the CPU 301 will be described in detail with reference to FIG. 7 and subsequent figures. The control by the CPU 301 is started at the same time when the power of the pachinko machine 1 is turned on, and a main routine in which the processing is repeatedly executed as long as the power is turned on,
There are other subroutines.

Main Routine First, the main routine (so-called general flow) will be described with reference to FIG. As described above, this routine is repeatedly performed after the power of the pachinko machine 1 is turned on. Specifically, the interrupt signal described below causes the routine to escape from the last stop state of the sequence and starts the program processing one sequence at a time. It is like this. The interrupt signal is issued every 2 ms. The main routine is Phase (PHASE) 1 to Phase (PHASE) 4
It is divided into.

When the main routine is started, first, in step S20, initial information is set (for details, refer to FIG. 8 described later). Next, in step S21, it is determined whether or not this time is power-on. If power is on, step S
In step 22, the initialization process, specifically, the RAM 303 check and the like are performed. At this time, for example, the variable display device 102
It is also possible to set a command to display an initial symbol (for example, "123") on the screen, or to set a flag, reset the output port 310, or initialize a subroutine. When the initialization process is completed, the process proceeds to step S23, the output process is performed, and the process proceeds to the next phase (PHASE) 3.

If the power is not turned on in step S21,
It branches to step S24 and executes a normal sequence. First, in step S24, prize ball control processing for exchanging prize ball data with the discharge control circuit is executed, and step S24
In 25, a three-step setting process of jackpot probability or a six-step setting process of reach determination probability is performed (details will be described later in a subroutine). Next, in step S26, an output process for outputting the output data set by the various subroutines is performed, and in step S27, a big hit random number, a reach determination random number, a stop symbol generation random number, and the like are updated. Then, step S2
At 8, input processing for removing chattering of various switches and logical conversion is executed. In this way, the phase (P
HASE) 1 processing is executed.

After step S28, the phase (PHASE) 2 is entered. First, step S30
To perform power fail processing. This is to monitor the power supply voltage of the lamp power supply, the solenoid power supply, etc., and turn off the output of the lamp and the solenoid when the voltage drop is confirmed. Next, in step S31, a prize monitor process of the count switch 323 in the variable prize device 104 is performed, and in a step S32, a continuous switch prize monitor process in the variable prize device 104 is also performed. Then, step S3
At 4, the special symbol actuation switch (first type starting opening) winning a prize monitoring processing is performed. In this way, the phase (PHASE)
The process 2 is executed.

Then, the device control process of the phase (PHASE) 3 is started. First, in step S36, the time-division branching process (specifically, branching by the value of the event counter).
I do. This is to take out the value of the event counter and branch to the step corresponding to the value.
For example, when the value of the event counter (EVENT) is 0, the process proceeds to the illegal processing step, and when the value of the event counter (EVENT) is 1, the process proceeds to the game processing (special figure game processing) step, and the value of the event counter is displayed. (EVE
When NT) is 2, the process proceeds to the solenoid edit process step, and when the event counter value (EVENT) is 3, the process proceeds to the lamp and LED process step.

In step S38, illegal processing is performed. This is a fraud detection, and when a fraud condition is generated, a fraudulent operation (for example, the special winning opening solenoid 3
31 is turned off, and a lamp indicating injustice is blinked). Specifically, for example, the count switch 323 is monitored for fraudulent non-counting, fraudulent jamming, and the like, as well as for reporting the fraudulent state. In step S40, special figure game processing is performed. This is to execute a game of special symbols, such as normal display of special symbols, variable display of special symbols, determination of big hit symbols, fanfare display, and out-of-range display.

In step S42, solenoid edit processing is performed. This is a process of setting ON / OFF information of each solenoid corresponding to various games, and a process of setting ON / OFF information of a starting opening winning signal to the outside. As a result, for example, when a big hit occurs, the big winning opening solenoid 331 is turned on to open the attacker (variable winning device) 104.

In step S44, lamp and LED processing is performed. This is the various lamps 33 on the game board 13.
2. Display information is set in the LED 331 corresponding to the game state. That is, various lamps 3
32, the necessary blinking editing is performed on the LED 331. In this way, the processing of phase (PHASE) 3 is executed.

Next, the phase (PHASE) 4 display control, sound editing, and output processing are carried out. First, in step S46, display control processing is performed. This transfers necessary control data to the display control circuit 354. Next, in step S48, sound editing and output processing is performed. This is for performing output editing of a sound (for example, a sound effect) and its output processing. As a result, the sound generator 312 generates a sound effect necessary for the game (for example, a fanfare operation sound), or a sound effect at the time of a big hit or a reach. Then, the CPU 310 enters the stopped state, and the main routine is repeated by exiting from the stopped state based on an interrupt signal described later.

Partial Detailed Subroutine of Phase (PHASE) 1 Next, FIG. 8 shows the phase (PHASE) of the main routine.
It is a figure which shows the detailed subroutine from step S20 to step S26 in 1. First, step S10
Set the stack pointer at 0. Thus, by setting the stack pointer every time, even if the stack is broken during one sequence due to noise or the like, it is possible to prevent the other memory areas from being broken.

Then, in step S102, the internal RAM 3
03 access is permitted, and in step S104, PCT1
Reset the interrupt signal of. The PCT1 interrupt signal is the time (2 ms) preset in the internal timer.
Is a signal that is output after the elapse of time, and the CPU 301 exits the stopped state based on this interrupt signal to start the program processing one sequence at a time. Therefore, it is necessary to reset this internal timer every time.

Next, in step S106, the value of the refresh register stored in the RAM 303 at the end of the sequence is read and written in the refresh register again. In step S108, it is determined whether or not the power is on. If the power is not turned on, the process advances to step S110 to check whether the check data set at the end of the sequence for checking the RAM 303 is broken (that is, RA).
It is determined whether the M inspection area is normal), and if it is broken, the process proceeds to step S122.

On the other hand, if the check data is not damaged (the RAM inspection area is normal), step S112.
Then, it is determined whether all the check data have been determined (whether all RAM areas have been checked). If not, the process returns to step S110 to repeat the process to determine the remaining check data. . When all the check data are determined, the process proceeds to step S114. The check data is stored in the RAM 303 at the beginning, the middle, and the last three locations.

Next, in step S114, SV control is performed. This executes a communication process for exchanging prize ball data with the discharge control circuit. Next, in step S116, probability setting / display processing is performed. Thereby, the control of writing, reading, and displaying the data of the jackpot probability and the reach rate set by the probability setting switch is performed.

Next, in step S118, it is determined whether or not the wait time at power-on has ended. The wait time when the power is turned on is EEPR when the power is turned on.
The probability value set in the OM304 is read, the value is stored in the internal RAM 303, and the EEPROM is read again.
For the delay time generation processing necessary to read the probability value set in 304 and compare it with the value stored in the internal RAM 303, and to confirm the operation to the EEPROM 304. belongs to. It also serves as a branch process for preventing the game from proceeding during the probability setting. Step S118 during probability setting
The determination result of is NO.

If the determination result in step S118 is YES, the process proceeds to step S120, and the output data set in each subroutine is output. Then, it progresses to step S27 of a main routine. In addition, step S11
If the determination result in 8 is NO, the process jumps to step S126 to update the wait time (delay time) at power-on, then the output process is performed in step S128, and then the process proceeds to step S38 of the main routine.

On the other hand, if it is determined in step S108 that the power is on, the process proceeds to step S122.
Initialize the area of the AM 303. Then, step S1
At 24, various built-in registers of the CPU 301 are initialized. Then, it progresses to step S126. In this way, step S20 in phase (PHASE) 1
~ The process of step S26 is performed.

Random Number Update Process Next, FIG. 9 shows the phase (PHASE) of the main routine.
It is a figure which shows the detailed subroutine of the random number update process of step S27 in 1. First, the big hit probability generation random number set in step S140 is updated. Next, in step S142, the probability generation random number for reach determination (which can be set in 6 steps from the outside) is updated. The random number for reach determination is used at the time of reach determination, and its setting method will be described later.

Next, in step S144, switch input processing is performed (CALL is performed), and in step S146, the symbol display counter is updated. This is for updating the three symbols of the special figure, and the three symbols are updated in a time division manner. Specifically, one symbol is updated in one sequence, and three symbols are updated in three sequences. Next, in step S148, the updated three symbols (special symbols) are determined, and in step S150, it is determined whether or not the combination of the big hit symbols (three symbols are the same).

If it is a combination of big hit symbols, the process proceeds to step S152, the address of the big hit symbol area is set, and the process proceeds to step S160. If it is not a combination of big hit symbols, the process branches to step S154 to determine whether or not it is a combination of reach symbols. For example, the left symbol and the middle symbol are the same, and it is determined whether or not the reach is reached. If it is a combination of reach symbols, the process proceeds to step S156, the address of the reach symbol region is set, and the process proceeds to step S160. If it is not a combination of reach symbols, the process proceeds to step S158, the address of the detached symbol region is set, and the process proceeds to step S160.

In step S160, the symbols corresponding to the address areas set in the jackpot pattern, the reach symbol, and the out symbol are stored, that is, the display symbol update result is stored. Then, it transfers to step S30 of a main routine. In this way, the result for the big hit determination can be immediately replaced with the stop symbol. Further, at the time of the reach determination, if the reach is determined, the stop symbol can be immediately exchanged for the reach symbol.

Probability Setting Display Process FIG. 10 is a diagram showing a detailed subroutine of step S116 in which the reach determination probability and the big hit probability are set. First, steps S200 to S208
Input processing of the probability setting switch 325 and the probability setting value display switch 326 is performed. That is, step S20
The physical state of each switch is read with 0, and step S20
At 2, the active logic is converted to positive logic. Next, chattering removal processing is performed in step S204, and the current logical state is calculated in step S206. Next, in step S208, the current state is stored. In this way
Chattering removal of each switch, logic conversion, etc. are performed,
Information from the switch is captured.

Here, the jackpot probability can be set in three steps, and can be changed to the following values, for example. (Setting 1) …… 5/1313 (Setting 2) …… 5/1417 (Setting 3) …… 5/1534

Further, the reach determination probability is set in six steps,
For example, it can be changed to the following values. (Setting 1) ...... 1/5 (Setting 2) ...... 1/10 (Setting 3) ...... 1/15 (Setting 4) ...... 1/20 (Setting 5) ...... 1/25 (Setting 6) ... … 1/30

Then, in the EEPROM 304, any value of (setting 1) to (setting 3) is written as the jackpot probability, and any value of (setting 1) to (setting 6) is written as the reach determination probability. And according to that value, step S
The big hit random number and the reach judgment random number are updated in the random number updating process 27.

Next, in step S210, branching is performed according to the step number. In branch processing, for example, a step vector is calculated by calculating a jump vector from the address table corresponding to the execution step number and jumping to the target address. In the step branch, the process proceeds to the process of the corresponding step number among the eight probability setting processes of step STEP-0 to step STEP-7. Then, the process returns to the main routine.

The contents of the branch destination will be briefly described below. STEP-0: EEPROM3 shows the setting probability when the power is turned on.
It is read from 04 and it is confirmed whether or not the setting probability (big hit probability and reach determination rate) is changed. STEP-1: Probability setting switch-X (switch for setting the jackpot probability) is monitored off.

STEP-2: The jackpot probability is set. STEP-3: Write setting data. STEP-4: Confirm write data.

STEP-5: Probability setting switch-X (switch for setting jackpot probability) is monitored. STEP-6: Probability setting switch-Y (switch for setting reach probability) is turned off. STEP-7: Set the reach determination probability.

Next, step STEP-0 to step S
The detailed processing contents of TEP-7 will be described. Setting Probability Reading Process FIG. 11 is a step STEP- in the probability setting display process.
It is a figure which shows the detailed subroutine of 0. First, in step S250, a read process to the EEPROM 304 is called (details will be described separately). Then, step S
The data read from the EEPROM 304 in 252 is stored in the internal RAM 303, and step S254 is performed again.
Calls the read processing to the EEPROM 304.
Next, the data read in step S256 is compared with the data stored in the internal RAM 303, and E
Whether or not the set value read from the EPROM 304 is correctly read is determined by reading twice.

As a result, when it is determined that the data has been correctly read and is normal, the process proceeds to step S258. However, when it is determined in step S256 that the data has not been correctly read, the process of PSS500 is performed, and the probability setting display process is ended. Then, in step S27 (random number updating process), the ROM 30
The original standard set value stored in 2 is read, and a game is played with the set value. In step S258, data switching information is set, and in step S260, it is determined whether or not the probability setting switch-X (switch for setting the jackpot probability) is turned on. In this case, it is determined whether or not the jackpot probability is set. To set the jackpot probability, turn on the probability setting switch-X and turn on the power supply.

If the probability setting switch -X is ON, the process proceeds to step S262 to set the probability setting flag, and the 5 second timer is set in step S264. This timer is used for 5 seconds to consider that the setting is completed when the probability setting switch-Y is not input. Then, step S
In 266, change the step number to “1” and change the PSS410.
Jump to.

If the probability setting switch -X is off in step S260, the process proceeds to step S268 and the probability setting switch -Y (switch for setting reach probability).
It is determined whether or not is on. In this case, it is determined whether or not the reach determination probability is set.
When it is desired to set the reach determination probability, the probability setting switch-Y is turned on and the power is turned on.

If the probability setting switch -Y is on, the flow advances to step S270 to set a 5-second timer. This timer is used for 5 seconds to consider that the setting is completed when the probability setting switch-X is not input. Then, in step S272, the step number is changed to "6" and PS
Jump to S410. On the other hand, if the probability setting switch-Y is off in step S268, the process jumps to PSS260.

In the probability setting display process by executing the above steps, the following probability settings are made. A. When the probability setting switch -X is turned on and the power is turned on, the big hit probability is set. At this time, if the jackpot probability is set, the setting probability is updated by operating the probability setting switch-Y, and if the update by the probability setting switch-Y is not recognized for 5 seconds, the updated value becomes the setting value and is stored in the EEPROM 304. While being written, the big hit random number is updated with the set value. The update by the probability setting switch-Y is repeated in a loop of (setting 1) → (setting 2) → (setting 3) → (setting 1).

B. When the probability setting switch-Y is turned on and the power is turned on, the reach determination probability is set. At this time, if the reach determination probability is set, the setting probability is updated by operating the probability setting switch -X, and if the update by the probability setting switch -X is not recognized for 5 seconds, the updated value becomes the set value, and the EEPROM 304 And the reach determination random number is updated with the set value. The update by the probability setting switch-X is repeated in a loop of (Setting 1) → (Setting 2) → (Setting 3) → (Setting 4) → (Setting 5) → (Setting 6) → (Setting 1).

Probability Setting Switch-X Off Monitoring Process FIG. 12 shows a step STEP in the probability setting display process-
It is a figure which shows the detailed subroutine of 1. First, in step S280, it is determined whether the probability setting switch -X is on. If not turned on, step S28
In step 2, the step number is changed to "2" and the process jumps to PSS410. If the probability setting switch-X is on, the process jumps to PSS500. In this way, the OFF of the probability setting switch -X is monitored.

Big hit probability setting process FIG. 13 shows a step STEP- in the probability setting display process.
It is a figure which shows the detailed subroutine of 2. First, in step S300, it is determined whether or not there is an input edge (rising edge) of the probability setting switch-Y. If a rising edge is detected, one big hit probability setting mode is updated in step S302. For example, when it is set in (Setting 1), it becomes (Setting 2).

Next, in step S304, it is determined whether or not the jackpot probability setting mode is equal to or more than the upper limit value. If it is equal to or more than the upper limit value, the jackpot probability setting mode is returned (that is, cleared) to the initial value in step S306. Since the jackpot probability setting mode has three stages, the upper limit is (setting 3),
The initial value is (Setting 1). If the jackpot probability setting mode is not equal to or more than the upper limit value, step S306 is skipped and the process proceeds to step S308. In step S308, switching information is set. Then, in step S310, 5
The second timer is set, and it is determined in step S316 whether or not the 5-second timer has timed out. The 5-second timer is initialized every time the probability setting switch-Y is input.

On the other hand, if the input edge of the probability setting switch-Y is not detected in step S300, step S300
In step 310, the input level state of the probability setting switch-Y is monitored. This is for determining whether or not the setting state is being set (the big hit probability is being set). The set value is updated at the input edge, and the level is ignored. Step S31
When it is 0 and the input level of the probability setting switch-Y is on, it is in the setting state, and therefore the process proceeds to step S314 in order to reset the 5-second timer in order to avoid updating the 5-second timer. Further, when the input level of the probability setting switch-Y is off, it is not in the setting state, so the process proceeds to step S312, the 5 second timer is updated, and then the step S316.
Proceed to.

In step S316, it is determined whether or not the 5-second timer has expired. If not, the process jumps to PSS500. If completed, step S318
Go to. Note that step S318 is the jump destination of PSS 260. In step S318, it is determined whether or not the switching information is set (whether the probability setting mode is switched). If YES, the switching information is cleared in step S322. Then, in step S324, EEP
The writing standby information for the ROM 304 is set, and the writing process is called to the EEPROM 304 in step S326. The details of the writing process to the EEPROM 304 will be described later.

Then, in step S328, the step number is set to "3" and the process jumps to PSS410. If NO in step S318, step S320
Go to, set the step number to "5" and set PSS41
Jump to 0. In this way, the jackpot probability is set.

Setting Data Confirmation Process FIG. 14 shows a step STEP- in the probability setting display process.
It is a figure which shows the detailed subroutine of 3. First, in step S350, the writing information to the EEPROM 304 is set, and in step S352, the writing process to the EEPROM 304 is called. Next, in step S354, the step number is set to "4" and the process jumps to PSS410. In this way, the setting data is written in the EEPROM 304. Note that the jackpot probability setting value is written from PSETP3, and the reach determination probability value is written from PSETP7 (which will be described in detail later).

Write Data Confirmation Process FIG. 15 shows a step STEP- in the probability setting display process.
It is a figure which shows the detailed subroutine of 4. First, in step S360, the reading process of the EEPROM 304 is called, and in step S362, the data once written in the EEPROM 304 is read again and compared with the data stored in the internal RAM 303 to check whether the data is normal (OK).
Determine) If the data is OK, write prohibition information is set in the EEPROM 304 in step S364, and the write processing to the EEPROM 304 is called in step S366. As a result, the EEPROM 30
The write-protection information is written in 4, and the writing is completed.

Then, the step number is changed to "5" in step S368, the step number is stored in step S370, and the process jumps to PSS500. Note that step S370 becomes the jump destination of PSS410. On the other hand, if NO in the above step S362 (when the data is not OK), the process branches to step S372 to change the step number to “3”, and then the process proceeds to step S370.
Therefore, since the data was not written normally,
The process of PSTEP3 will be performed again. In this way, whether or not the written data has been normally written in the EEPROM 304 is confirmed for each writing.

Probability Setting Switch-X Input Monitoring Process FIG. 16 shows step ST- in the probability setting display process.
It is a figure which shows the detailed subroutine of 5. First, the probability setting flag is cleared in step S400, and then step S4
In 02, it is determined whether or not the probability setting switch-X is turned on. When it is on, the process proceeds to step S404,
The lighting information of the 7-segment LED is set, and the process proceeds to step S406 to perform the lighting process of the 7-segment LED. Then, the process returns to the main routine. As a result, the current setting value (big hit setting value and reach judgment value)
Display data is set, and the 7-segment probability setting display LEDs 232 and 233 LEDs are lit up and displayed.

On the other hand, if the probability setting switch -X is not turned on in step S402, the process branches to step S408 to set the OFF information of the 7-segment LED, and the process proceeds to step S406. Therefore, at this time, the probability setting display LEDs 232 and 233 do not light up. Note that step S406 is the jump destination of PSS500. In this way, by turning on the probability setting switch -X, it is possible to confirm the current setting value (when the probability setting switch -X is turned on after the power is turned on, the current setting value (big hit setting value and reach determination value ) Is displayed).

Probability Setting Switch-Y Off Monitoring Process FIG. 17 shows step ST- in the probability setting display process.
It is a figure which shows the detailed subroutine of 6. First, in step S420, it is determined whether or not the probability setting switch-Y is turned on. If not, the process proceeds to step S422, the step number is changed to "7", and then the PSS
Jump to 410. On the other hand, when the probability setting switch-Y is on, the process jumps to PSS500. In this way, the probability setting switch-Y is monitored for OFF.

Reach Judgment Probability Setting Process FIG. 18 shows a step STEP- in the probability setting display process.
It is a figure which shows the detailed subroutine of 7. First, in step S500, it is determined whether or not there is an input edge (rising edge) of the probability setting switch-X. When the rising edge is detected, one reach reach probability setting mode is updated in step S502. For example, when it is set in (Setting 1), it becomes (Setting 2).

Next, in step S504, it is determined whether or not the reach determination probability setting mode is greater than or equal to the upper limit value, and if it is greater than or equal to the upper limit value, the reach determination probability setting mode is returned to the initial value (that is, cleared) in step S506. . Since the reach determination probability setting mode has six levels, the upper limit value is (setting 6) and the initial value is (setting 1). If the reach determination probability setting mode is not the upper limit value or more, step S
Jump 506 and proceed to step S508. In step S508, switching information is set. Then, in step S510, a 5-second timer is set, and in step S51
At 6, it is determined whether or not the 5-second timer has timed out.
The 5-second timer is initialized every time the probability setting switch-X is input.

On the other hand, if the input edge of the probability setting switch -X is not detected in step S500, step S500
Proceeding to 512, the input level state of the probability setting switch-X is monitored. This is to determine whether or not the setting state is being set (the reach determination probability is being set). The set value is updated at the input edge, and the level is ignored. Step S
If the input level of the probability setting switch -X is on at 512, the setting state is in progress, so in order to reset the 5-second timer in order to reset the 5-second timer, step S51
Go to 0. Further, when the probability setting switch-X input level is off, it is not in the setting state, so step S514
Proceed to step S51 to update the 5-second timer, and then
Go to 6.

In step S516, it is determined whether or not the 5-second timer has expired. If not, the process jumps to PSS500. If completed, step S518
Go to. In step S518, it is determined whether or not the switching information is set (whether the probability setting mode is switched). If YES, the switching information is cleared in step S520. Then, in step S522, EEPRO
The write standby information for M304 is set, and the write processing is called to the EEPROM 304 in step S524. The details of the writing process to the EEPROM 304 will be described later.

Then, in step S526, the step number is set to "3" and the process jumps to PSS410. If NO in step S518, step S528
Go to, set the step number to "5" and set PSS41
Jump to 0. In this way, the reach determination probability is set.

EEPROM Read Processing FIG. 19 shows the EEPR shown in step S254 of FIG.
It is a figure which shows the detailed subroutine of the reading process (ROMR) of OM304. First, a read command is set in step S550, and EEPRO is set in step S552.
The writing process of M304 is called, and the EEPROM30
Read from 4. Then, step S55
The read bit length is set in step 4, and 1 bit of data is read in step S556. Next, in step S558, the read data is stored in the register, and in step S56
At 0, it is determined whether or not the reading of the bit length data set previously is completed. If the reading is not completed, the process returns to step S556 to repeat the loop, and when the reading is completed, the process returns.

EEPROM Writing Processing FIG. 20 shows the EEPR shown in step S326 of FIG.
It is a figure which shows the detailed subroutine of the write-in process (EEPOUT) of OM304. First, in step S600, writing to the EEPROM 304 is set in a standby state, and in step S602, it is confirmed whether the writing is OK. If writing is not OK, the process waits until it becomes OK, and if it becomes OK, the process proceeds to step S604, and the bit length of the write data is set.

Then, a start bit is set in step S606, and 1 bit is written in step S608.
Then, in step S610, it is determined whether or not the writing of the data having the bit length set previously is completed. If the writing is not completed, the process returns to step S608 to repeat the loop, and when the writing is completed, the process returns.

[0129] special symbol game processing Next, FIG. 21 Japanese view game processing of the main routine (BL
It is a figure which shows the detailed subroutine of OCK2: step S40). First, in step S700, it is determined whether or not the sequence is switched (whether the sequence timer has expired). If the sequence is not switched, step S700
The sequence timer is updated at 702, and then the process proceeds to step S46 of the phase (PHASE4) of the main routine.

If the sequence is switched in step S700, the process branches to step S704 to determine whether or not the current step number is an inappropriate execution step number. If not, the process proceeds to step S706. Initialize the execution step number. On the other hand, if the current step number is not inappropriate, step S706 is skipped and the process directly proceeds to step S708. Step S
At 708, processing for branching to each step processing is performed. In this way, even if the memory in which the step number is stored is broken and an inappropriate value is written, a measure is taken so that no trouble occurs.

In the branch processing by the step number in step S708, a step vector is calculated by calculating a jump vector from the address table corresponding to the execution step number and jumping to the target address. In step branching, steps STEP-10 to
Proceed to the process of the corresponding step number of the 14 game processes consisting of step STEP-1D. Then, it transfers to step S46 of a main routine.

The contents of the branch destination will be briefly described below. STEP-10: This is a process for performing a normal operation. The storage information is set in the display control area, and the special figure rotation sound at high probability and low probability is set. STEP-11: This is a process for monitoring the end of the automatic stop time, and specifically, processes such as determination of the big hit random number value captured in step S34 and determination of the stop symbol are performed.

STEP-12: Stop monitoring of the first symbol is performed. STEP-13: Stop monitoring and reach determination of the second symbol are performed, and further, the stop symbol is lucky NO. Is determined.

STEP-14 (other than reach): Judgment of the stop result, that is, judgment of whether or not the stop symbol is a big hit, initialization processing at the time of a big hit, etc. are performed, and particularly judgment processing other than reach is performed. STEP-15 (at the time of reach): Similarly, determination of the stop result,
That is, it is determined whether or not the stop symbol is a big hit, initialization processing at the time of a big hit, etc., and particularly determination processing at the time of reach. STEP-16: The removal operation is performed, and the processing when the stop symbol is the removal operation is performed.

STEP-17: The end of the fanfare operation is monitored, and the initialization processing of the next big hit operation is performed. STEP-18: The end of the second half of the interval operation is monitored, and the initialization processing of the next big hit operation is performed. STEP-19: The big hit operation before the continuation is performed, and the operation process before and after the winning of the continuation switch 322 in the special winning opening is performed.

STEP-1A: Performs a jackpot operation after continuation, and performs operation processing before and after winning the continuation switch 322 in the special winning opening. STEP-1B: To monitor the end of the effective time, 1
Performs the end monitoring process of the big hit operation once. STEP-1C: Monitor the end of the first half of the interval. STEP-1D: The end of the big hit ending operation is monitored. Specifically, the big hit ending operation is monitored until the last big hit operation or until a puncture.

22. Automatic Stop Time End Monitoring Process Next, FIG. 22 is a diagram showing a detailed subroutine of STEP-11 (automatic stop time end monitoring process) which is the basis of the present invention. First, in step S800, a stop symbol fetching process is called. In this stop symbol capture process,
Judgment whether or not the big hit random number that has been taken in is a big hit, and the stop symbol is decided based on the judgment result. Next, in step S802, the symbol determination process is called and step S
Proceed to 804. With the symbol determination process, the stop symbol data is taken out, whether the stop symbol is a big hit symbol, or a lucky number.
It is to determine whether it is a design.

In step S804, the previous step S80
It is determined whether or not it is a big hit (whether the big hit flag is set) based on the result of the determination made in step 2. If NO, the process proceeds to step S806 to fetch the reach determination random number, and whether or not the reach is reached in step S808 ( Judgment is made (whether the reach judgment random number is hit). When it is not reach, the detachment stop design is fetched in step S810 and is stored in the stop design area in step S812. Next, in step S814, a disconnection command is set, and the process proceeds to step S816.

On the other hand, if YES at step S804,
Alternatively, if YES in step S808, the flow advances to step S822 to determine again whether or not there is a big hit flag. If there is no big hit flag, in step S824 the reach symbol is fetched from the area where the reach determination stop symbol is stored, the reach symbol fetched in step S826 is written in the stop symbol area, and the process proceeds to step S828. If YES in step S822, steps S824 and S826 are skipped and the process proceeds to step S828.

Here, in the prior art, since it was determined whether or not the reach was reached only by the determination of the design created as the stopped design, the reach appearance rate was uniform (random).
On the other hand, in the present embodiment, by using a random value that can be set for reach determination (six steps), it is possible to set the reach appearance rate according to the business policy according to the preference of the hall, and the player. The interest of can be increased.

In step S828, it is determined whether or not it is a super reach. Superreach has a certain probability (eg,
It appears with a predetermined probability of 1/2. Step S832 for super reach
And set super reach command in step S816.
Proceed to. If not super reach, step S
Set a normal reach command at 830 and step S8.
Proceed to 16. In step S816, frame feed information is set, and in step S818, next step information is set.
Next, in step S820, the sequence time is calculated from the frame feed information, and in step S834, the step number switching flag is set. Then, in step S836, the control number switching process is called, and the process proceeds to step S46 of the main routine.

As described above, in the present embodiment, the predetermined 6-step set values are provided for the reach determination, and it is possible to freely set any one of the set values by the staff, so that the appearance rate of the reach symbol is not uniform. , The game can be very interesting.
As a result, the reach appearance rate can be set according to the business policy of the hall, and the flexibility of the business form of the hall can be increased.

Further, different reach occurs even with the same type of game machine, which can further increase the interest of the player. Furthermore, once set, the storage means (EEPRO
Since there is M), there is an advantage that it is not necessary to remember every day. In addition, since the jackpot probability is also provided with a setting function of three stages, the following combinations can be made, and different gaming characteristics can be imparted to the same type of gaming machine.

That is, the jackpot probability has three levels, and as described above, it can be set to each value of (Setting 1) .. 5/3313 (Setting 2) .. 5/1417 (Setting 3) ....... 5/1534. On the other hand, the reach determination probability has six levels, and as described above, (setting 1) ... 1/5 (setting 2) ... 1/10 (setting 3) ... 1/15 (setting 4) ... 1 / 20 (Setting 5) ...... 1/25 (Setting 6) ...... It can be set to each value of 1/30, so by combining these values with each other, a total of 18 types of amusement in the same model Can have

Further, the following effects can be obtained. (I) Since the jackpot probability setting and the reach determination probability setting are set separately, there is no need to set both at the same time, which is convenient. For example, normally, once the jackpot probability is set, it is rarely set again. This is because the business policy cannot be decided unless data is collected over a long span. (II) Since the jackpot probability setting process and the reach determination probability setting process are performed using the same subroutine, the program capacity can be reduced.

(III) Since the reach determination probability can be set by using the jackpot probability setting switch (usually a switch used for this purpose), the hardware configuration is prevented from becoming complicated and the hardware cost is reduced. Can be reduced. (IX) Since there is a function of displaying the current state of the jackpot probability setting value and the reach determination probability setting value, the current setting value can be easily confirmed.

The present invention can be implemented in various modifications as described below. A. In the present invention, the jackpot probability setting and the reach determination probability setting are configured to be set separately, but the purpose of the present invention is to provide the reach with a predetermined determination probability, Therefore, with the jackpot probability setting,
The reach determination probability setting may be performed simultaneously (bearing). For example, as an example of simultaneous execution,
There are the following modes. (Setting 1): Big hit probability: 5/1313 and reach determination probability: 1/5 (Setting 2): Big hit probability: 5/1417 and reach determination probability: 1/15 (Setting 2): Big hit probability: 5 / 1534 and reach determination probability: 1/30

B. In the reach determination probability setting function of the present invention,
You may set the sound and display data corresponding to each reach determination setting value. For example, since the sound and display data are stored as table data corresponding to each processing such as when the special drawing is rotated and when the special drawing is stopped, if the reach determination setting value is (setting 3), it corresponds to it. This can be easily realized by setting the sound and display data as a data table in advance. C. Even if the reach is commonly used, it is possible to further enhance the playability by providing such a setting function. Specifically, the variations of games on the same model will increase.

D. Even if the reach is used for other symbols, if such a setting function is provided, the playability can be further enhanced, and similarly, the variation of the game with the same model is increased. E. The numerator of the reach determination probability may be fixed to 1, and the denominator may be added or subtracted one by one so as to be set in multiple stages. Further, such a method may be used for setting the jackpot probability. However, it is within the upper and lower limits. F. The variable display device may be a fluorescent display tube, a color liquid crystal display, a TV set, or another display device. The point is that it can display various types of game information. G. In the first type gaming machine, starting memory is performed up to four, and the stop symbol is determined by the prize fetch. At this time, the reach determination probability may be set for the starting memory. Doing so will make the game even more diverse and interesting.

It goes without saying that the present invention can be applied to a pachinko machine which is not equipped with a card reader. Further, the gaming machine according to the present invention is not limited to the example applied to the prepaid card type pachinko machine as in the above embodiment. For example, it can be applied to a credit-type pachinko machine. Further, it can be widely applied not only to the prepaid card system but also to a pachinko machine that requires no card at all.

[0151]

According to the present invention, a set value at a predetermined stage is provided for reach determination, and it is possible to freely set any one of the set values, so that the appearance rate of the reach symbol is not uniform and the game is extremely Can be interesting to you. Therefore, it is possible to set the appearance rate of the reach according to the business policy of the hall, and it is possible to increase the degree of freedom of the business form of the hall.

Further, different reach may occur even with the same type of game machine, and the interest of the player can be further increased. Furthermore, once set, there is a storage means (EEPROM), so that it is not necessary to store the data every day. In addition, since the jackpot probability setting and the reach determination probability setting are set separately, it is not necessary to set both at the same time, which is convenient.
